Simona (Serena Grandi) is married to Marco who neglects her. Growing dissatisfied, she provokes her husband by readily accepting the many sexual advances of friends and strangers. Then, to satisfy her increasingly depraved and perverse desires, she seeks night-time partners leading to ever riskier and sometimes violent encounters. Lady of the Night comes from Tinto Brass' producer Giovanni Bertolucci (The Key, Miranda, Capriccio, Po Box Tinto Brass, Lola, Private) bearing all of his trademarks. It is a typically Tintoesque story of a young woman's search for sexual fulfillment, starring Serena Grandi, the voluptuous star of Tinto Brass' 'Miranda'.
